Perspective: Warning label could limit misuse of automated valuations

Automated valuation models, known as “AVMs,” aren’t new. In fact, lenders and appraisers have used these computer-generated estimates of property values for some years as both a supplement to and substitute for an opinion of value prepared by a state-licensed appraiser.

So why has the state of Arizona turned Zillow’s “Zestimates,” which differ little if at all from other automated valuations, into a political ping-pong ball?
